Science Experiments For Kids:How To Make An Easy Lava Lamp

You'll find making a lava lamp in our free e-book of the TOP TEN easy kids science experiments - that won't let you down!

Making your own homemade lava lamp has everything you would hope for in a kids science experiment.

It's:

Cheap

Easy

Has the essential WOW! factor

Teaches the wonder of science

You'll have fun too

AND

There's a FREEinstruction sheet which you can print out

You'll also find we've added a few secret homeschool tricks to make your experiment even more child friendly!

You can see how it works here:

Easy Science Experiments

When it comes to science experiments for kids, simple is best. You'll find most of the ingredients you'll need in the kitchen.

Clear jar with lid (a soda bottle is fine)

Water

Cooking oil

Food coloring

Alka-seltzer tablets (salt will work - but not so well)

Homeschool Secrets

These are the extra ingredients you don't really need for this experiment but make it more fun!

Glitter

Sequins

Flashlight

Simple Science

Just like in the real homeschool lava lamp you can see above that we bought for William's birthday, the childrens lamp you'll be making will get globs of oil to move through water like an erupting volcano.

How To Make A Lava Lamp

Fill your jar or soda bottle three quarters full of oil.

Fill to the top with water.

Add some drops of food color to darken the water.

Divide your alka-seltzer tablet into 8 parts and drop one in.

Your lava lamp will start erupting.

You'll actually be proving that science experiments for kids are a great way of showing that the
Alka-Seltzer tablet reacts with water to make tiny
bubbles of carbon dioxide gas.

You can see the same effect if you try making a volcano - another of our favorite easy children's homeschool experiments.

Childrens Science Experiments

A great way to make homeschool science appeal to children is to make experiments fun! We did that by adding some reindeer and glitter into the mix.

See what happens to the Christmas tree:

Another way to make a lava lamp more realistic (and exploit your childrens love of playing in the dark) is to add a flashlight and shine the light through.

Home School Science

The great thing about science experiments for kids is that they make amazing the science around us.

Your experiment will have shown how oil and water are immiscible - they won't mix however hard you shake them!

The carbon dioxide bubbles attach themselves to the
blobs of colored water and cause them to float to the surface. When the
bubbles pop, the color blobs sink back to the bottom of the bottle.

You can see a full explanation of the science behind real lava lamps on Wikipedia, including having fun watching this lamp in action:
